When you tend to purchase aluminum expanded metal, expanded metal, safety grating and laser cut panel, you will be often asked what surface treatment do you want. Whether you have no idea about this question ? To solve your confusion, today I will introduce the differences of surface treatments. The most widely used surface treatment include Powder Coated, PVDF, Anodizing and Galvanized. About the detailed information, please check the following:
| Surface Treatment | Picture | Introduce |
| Powder Coated |  |
Powder coating process: raw materials-cleaning (acid washing-water washing-chromizing-water washing-water washing)-drying naturally-hanging up -coating room-powder coating-baking-hanging down-packing-delivery. Powder coating is suitable for both interior and exterior decoration. Powder coating is cheaper than PVDF, but has great effect. |
| PVDF |  |
Fluorocarbon coating process: raw materials-cleaning (acid washing-water washing-chromizing-water washing-water washing)-drying naturally-hanging up -coating room - the first coating-the second coating-the final coating-baking-hanging down -packing- Ship. Three times coating: primer, topcoat and varnish. PVDF is widely used in exterior decoration. PCDF looks more metallic. |
| Anodizing |  |
Anodizing process: raw materials - cleaning ( alkali washing-water washing)- oxidation tank - hanging up 鈥?nbsp;oxidation - water washing-drying naturally-packing-delivery Since the pretreatment of anodizing is alkaline washing, we suggest choosing the natural aluminum color. We do not suggest using anodizing painting for outdoor decoration and it is ok for indoor use. |
| Galvanized |  |
Galvanizing is divided into cold galvanizing and hot galvanizing. The most commonly used technique is hot galvanizing. The production process of hot-dip galvanized sheet mainly includes: the preparation of original sheet- pre-galvanizing treatment-hot plastic dipping- post-galvanizing treatment -the inspection finished product, etc. The galvanizing is suitable for iron, carbon steel and has great anti-rust performance. |
The surface treatments are suitable for our all products. If any question, please don’t hesitate to contact me freely.
